Earthquakes Over the past five hundred years, Earthquake activity has increased tremendously. Even in 2015 Irving, Texas has had at least eighty nine earthquakes! Earthquakes are formed underground when tectonic plates begin to rub against one another. Earthquakes are starting to form and happen constantly because of many different reasons. One example being, fracking, which is the process of injecting liquid at high pressure into subterranean rocks, boreholes, etc., so as to force open existing fissures and extract oil or gas.

Seismic waves are made when some kind of energy stored in Earth’s crust. Natural events such as volcanic eruptions and meteor impacts can cause earthquakes, but most of the naturally-occurring earthquakes are activated by movement of the earth 's plate. The Haiti Earthquake included many details common to Earthquakes and caused damage and destruction to property and lives that affected the region, but the area has recovered in its after math. Many parts of this disaster are common to Earth Quakes like the Haiti Earth Quake .Haitian capital of Port-au-Prince was a part and was also hurt. The disaster was a Earthquake it

The earthquake happened because of the movement from the San Andreas Fault (u-s-history.com) .This little movement from the tectonic caused big things such as earthquake, but what exactly is San Andreas Fault? San Andreas fault is major fracture of the Earth’s crust in extreme western north America (Brittanica). San Andreas fault have caused so many earthquakes in U.S.A, causing many destruction, and causing lost of lifes. Now, What made Northridge Earthquake so destructive? While the Northridge earthquake was happening Californian people couldn’t predict it (u-s-history.com).

Many believe that this is the causation of many earthquakes that have occurred in the last years. Water contaminations are a possible risk of fracking. With all the chemicals used for oil fracking, it could cause harm the human body. Although it provides many jobs and gives us oil and natural gas, there are many factors of fracking that has harmed the environment. Oil fracking, also known as hydraulic fracking or hydrofracking, has been used for roughly 65 years to get natural gas.

This particular earthquake was the largest recorded earthquake for Japan prior to 2011 earthquake. 49 days after the Hoei earthquake, on 16 December 1707, Mount Fuji erupted from three vents located on its southeast flank [Tsuya, 1955]. This particular eruption was a plinian eruption that produced 0.7 km^3 of tephra [Miyaji and Koyoma, 2007], and the emission was of mixed and mingled andesitic and dacitic tephras that was then followed by basaltic tephra [Tsuya, 1955]. According to Chesley (2012), the conduit was opened and the basaltic magma was pushed out of the chamber by unclamping of the deeper dike along with compression of the basaltic magma chamber. This basaltic magma then moved up the dike from the basaltic chamber 20 km deep into the andesitic and dacitic magma chambers creating magma mixing and rapid vesiculation.

In North Carolina many of us have been effected in some way by tornados, hurricanes, and maybe even an earthquake, but I would bet that none of us have been effected by the worse natural disaster the tsunami. Historically, tsunamis have been caused by a plethora of different events. Some of these are underwater earthquakes, volcanoes, and landslides. Many people might recognize earthquakes as a violent shake in the earth’s crust and this is true, but tsunamis can be more powerful causing a greater damage. Tsunamis happen when the plates on the crust of the earth move, therefore moving the entire plate so that the water rises and is pushed forward, therefore causing a tsunami (Drohan, 2009, p.21).

The magnitude of the earthquake gave hint to the size and power of the San Andreas Fault, that was previously unknown. And while the extensive death tolls and damage made to the city was horrific, the better understanding and knowledge of how to properly build for the San Andreas earthquakes was priceless. The ‘Great Earthquake’ of 1906 was not only a massively impressive earthquake but it was also the creator of one of the most destructive fires in the history of the United States of

In 2003, there were several minor financial scandals involving insider information and bribery. In response, Lagos introduced new reforms promising greater transparency. In 2004, Chile passed a law permitting divorce for the first time. On February 27th, 2010, Chile was hit by an 8.8 magnitude earthquake,the fifth largest ever recorded at the time, for perspective. Fatalities were relatively low, with some 500 people killed in the devastation, most from the tsunami that resulted from the earthquake.The earthquake was also followed by multiple aftershocks.

There are a lot of unexpected thing happened to our life. The Valdivia earthquake and Alaskan earthquakes is the most strongest earthquakes that ever happen in the world and this earthquakes are giving both of the two country a very big impact to their population and economy, they also losing a lot of people, housed, money and a huge of the area that earthquakes happened got damage. By the way one of the American author, Thomas Sowell, had said that “All thing are the same except for the differences and different except for the similarities” and that it true however both of them are the top strongest earthquakes but they are some different and similarity between them. Valdivia earthquake and Alaska earthquake are happened in America. They have the same impact like secondary hazard.

An earthquake is a serious manner in which no one should take lightly. This earthquake was notable for its incongruity: it was one of the most powerful to hit New York City in decades, and yet it caused little damage. The likelihood of an earthquake in the New York metropolitan area has been assessed as ‘‘moderate’’ (Tantala, 2008, p. 812). However, New York City has experienced already three earthquakes and what are going to be the odds for another earthquake happening soon. According to Tantala (2008), although New York City is a region with low seismic hazard (infrequent damaging earthquakes), it actually has high seismic risk because of its tremendous assets, concentration of buildings, and the fragility of its structures, most of which have not been seismically designed (p. 813).
